| Clean ground @pauly When it comes to audio I’ll believe anything until proven otherwise. https://www.auralthrillsaudio.com/battac.htmAs for a "Clean Ground". I see you live in the NE. Assuming soil in your area is not excessively sandy and is black dirt and cl... | |
| Clean ground @pauly You said: Correct.Nothing touches a wall socket with the exception of the three prong plug that provides access to ground. I charge when I’m not listening.In the rare event that I want to take input from, or output to, a device that is plu... | |
| Over loading? danmar123 OP54 posts 08-16-2021 9:22am I (personally) ran 8/3 from my main, on a 60 amp breaker @danmar123 #8 awg cu wire is rated for 40 amps (60* C). Breaker should be 2 pole 40 amp. This is why I’m asking; I don’t want to harm my amps. No ... | |
| Over loading? Guys don’t forget to figure branch circuit wiring VD (Voltage Drop). Example: For a 60ft branch circuit using #14awg cu wire during short peaks of 12 amps current draw. Voltage drop: 3.85Voltage drop percentage: 3.21%Voltage at the end: 116.15 15 ... | |
| Over loading? fiesta75632 posts 08-16-2021 12:01am For me I changed my 15 amp breaker to 20 amps because it popped occasionally on power up only, never while playing loud. I had 9.6kW output into 4 ohms though... @ fiesta75 What is the branch circuit wiring s... | |
| Power conditioning for multiple dedicated circuits danvignau911 posts 08-13-2021 7:02am I hope you ran all four outlets to the same leg on your electrical panel. If not, do it. You will be pleasantly surprised, and all it takes is to switch the breaker around. It is not even necessary to remove ... | |
| How To Do You Measure the Quality of Your AC Power? What a freaking waste of time and money. None of these people will find anything wrong, because from their point of view there is nothing wrong. Multiple electricians have failed to find anything wrong with my electrical system or electrical pan... | |
| How To Do You Measure the Quality of Your AC Power? Hire a Power Quality Testing Company. Cost per hour $150 - $250. A heck of a lot cheaper than buying a Power Quality Analyzer. Example of a Power Quality Analzer: You would only need one for single phase power. https://www.myflukestore.com/categor... | |
| Power conditioning for multiple dedicated circuits To add to my last post. If a duplex receptacle is split and the two receptacles will each be fed by a separate branch circuit NEC 210.7 shall apply. (It doesn’t matter if one is fed from L1 and the other from L2 or both circuits are fed from two b... | |
| Power conditioning for multiple dedicated circuits I would be remiss if I did not mention if an Electrical Contractor/Electrician was hired to install four 120V branch circuits he/she would not install MWBC (s). The reason is the NEC requires all new 15A and 20A branch circuits supplying outlets, ... | |
| Power conditioning for multiple dedicated circuits dhite71 OP149 posts 08-08-2021 6:23pm I have been thinking more about my 12/3 wire configured for two separate circuits. There is a single neutral and ground wire going back to the panel. Does this matter when all neutral and ground wires in a h... | |
| Power conditioning for multiple dedicated circuits dhite71 OP147 posts 08-08-2021 12:23pm @jea48 I did the 2nd scenario you described. I chose this because when I went to Lowes to pick up the Romex they had a bundle of 12/3 wire that was 1/2 price due to a return. Ther... | |
| Power conditioning for multiple dedicated circuits builder3454 posts 08-08-2021 12:46pm I think you’ve now protected your 12 wire circuits with a 40A breaker, which is a huge mistake. Correct. The breaker needs to be a 2 pole 20 amp breaker. |
